On July 13, 2012, JPMorgan Chase & Co. (the Firm) issued a press release stating that the Firm had reached a determination to
restate the Firms previously-filed interim financial statements for the first quarter of 2012. The Firm reached the determination to restate on July 12, 2012, following management review of the matter with the Audit Committee of the
Firms Board of Directors. See Item 4.02(a) below for additional information about the restatement and related matters. A copy of the Firms press release announcing the restatement and related matters is attached hereto as Exhibit
99.1 and incorporated by reference herein.

The Exhibit provided with this Form 8-K has been furnished and shall not be deemed to
be filed for purposes of the Securities Exchange Act of 1934, as amended.

On July 13, 2012, JPMorgan Chase & Co. reported
that it will restate its previously-filed interim financial statements for the first quarter of 2012. The restatement will have the effect of reducing the Firms reported net income for the 2012 first quarter by $459 million. The restatement
relates to valuations of certain positions in the synthetic credit portfolio of the Firms Chief Investment Office. The Firms year-to-date principal transactions revenue, total net revenue and net income and the year-to-date principal
transaction revenue, total net revenue and net income of the Firms Chief Investment Office (CIO) will remain unchanged as a result of the restatement. The Firm reached the determination to restate on July 12, 2012, following
management review of the matter with the Audit Committee of the Firms Board of Directors on the same day.

The following summarizes the
estimated effects of the restatement for the first quarter ended March 31, 2012:

The restatement results from information that has recently come to the Firms attention in connection
with managements internal review of activities related to CIOs synthetic credit portfolio. Under Firm policy, the positions in the portfolio are to be marked at fair value, based on the traders reasonable judgment as to the prices
at which transactions could occur. As an independent check on those marks, the CIOs valuation control group (VCG), a finance function within CIO, verifies that the traders marks are within pre-established price testing
thresholds around external mid-market benchmarks and, if not, adjusts trader marks outside the relevant threshold. The thresholds consider market bid/offer spreads and are intended to establish a range of reasonable fair value estimates
for each relevant position. At March 31, 2012, the trader marks, subject to the VCG verification process, formed the basis for preparing the Firms reported first quarter results.

However, the recently discovered information raises questions about the integrity of the trader marks, and suggests that certain individuals may have been seeking to avoid showing the full amount of the
losses being incurred in the portfolio during the first quarter. As a result, the Firm is no longer confident that the trader marks used to prepare the Firms reported first quarter results (although within the established thresholds) reflect
good faith estimates of fair value at quarter end.

The Firm has consequently concluded that the Firms previously-filed interim
financial statements for the first quarter of 2012 should no longer be relied upon, and the Firm will be filing an amendment to its Quarterly Report on Form 10-Q for the quarter ended March 31, 2012, as soon as practicable, but not later than
it files its Quarterly Report on Form 10-Q for the quarter ended June 30, 2012. The financial statements included in the amended Quarterly Report on Form 10-Q will reflect adjusted valuations of the positions in the synthetic credit portfolio
as of March 31, 2012, based upon external mid-market benchmarks, adjusted for liquidity considerations. While there are a range of acceptable values for such positions, the Firm believes this approach represents an objective
valuation and is reasonable under the circumstances.

As a result of the restatement, the impact of the trading losses related to the
synthetic credit portfolio on the Corporate/Private Equity sector during the first quarter will increase, as noted in the table above, but this increase will serve to reduce the impact of these losses on the Corporate/Private Equity sector during
the second quarter by a corresponding amount. Accordingly, as noted above, CIOs year-to-date principal transactions revenue, total net revenue and net income and the Firms year-to-date principal transactions revenue, total net
revenue and net income will remain unchanged by the restatement.

The valuation errors had an immaterial effect on the Firms balance
sheet. CIOs Value at Risk model used, as inputs, independent marks for a majority of the positions in the synthetic credit portfolio and daily trader marks related to a limited number of positions in the portfolio. The

Firm believes that if CIOs VaR were re-calculated for the first quarter of 2012, the re-computed CIO VaR numbers would not be materially different from those reported in the Firms
Quarterly Report on Form 10-Q for the 2012 first quarter. At June 30, 2012, average VaR for CIO was $177 million for the quarter then-ended, and was $153 million for the six months then-ended. For the Firm, average total VaR was $201
million for the quarter ended June 30, 2012, and was $186 million for the six months ended June 30, 2012. For the same reason, the Firm believes the valuation irregularities had an immaterial impact on the Firms
risk-weighted assets. However, as a result of the restatement, the Firms Basel I Tier I common ratio will be reduced by 4 basis points to 10.3% and its Estimated Basel III Tier I common ratio will be reduced by 3 basis points to 8.1%, at
March 31, 2012.

Management has determined that a material weakness existed in the Firms internal control over financial reporting
at March 31, 2012. During the first quarter of 2012, the size and characteristics of the synthetic credit portfolio changed significantly. These changes had a negative impact on the effectiveness of CIOs internal controls over
valuation of the synthetic credit portfolio. Management has taken steps to remediate the internal control deficiencies, including enhancing management oversight over valuation matters. The control deficiencies were substantially remediated by
June 30, 2012.

Managements internal review of these matters is ongoing. If the Firm obtains additional information material to its
periodic financial reports, it will make appropriate disclosure.

Management has discussed these matters with its Board of Directors, and with
the Special Committee of the Board of Directors that is reviewing managements internal review. The Audit Committee has discussed the matters described in this Current Report with PricewaterhouseCoopers LLP, the Firms independent
registered public accounting firm.
